What Gases Are Used in Hospitals? Nick Vasco | 4 minutes | January 29, 2025 Hospitals mainly use six essential gases: Oxygen Nitrogen Nitrous oxide Helium Carbon dioxide Compressed air Each of these gases plays a crucial role in modern healthcare, from basic patient care to complex surgical procedures. In this guide, we’ll discuss their key applications, after which you’ll learn about the safety requirements and protocols to follow. WestAir supplies gas for hospitals across California and Arizona. Life-Saving Oxygen and Its Critical Applications Oxygen is the most commonly used medical gas, and it serves many critical purposes. It’s a literal lifesaver for patients with breathing difficulties and during surgical procedures. In emergency rooms, oxygen therapy helps stabilize patients experiencing trauma or severe respiratory distress. The gas is delivered through various methods, including: Nasal cannulas Face masks Ventilators Operating rooms rely heavily on oxygen during surgeries. Anesthesiologists carefully monitor oxygen levels to ensure patients maintain proper blood oxygen saturation throughout procedures. Oxygen isn’t just for direct patient care. It’s also essential in medical research labs, where it’s used in bioreactors and incubators to maintain cell cultures and tissue samples. Anesthetic Gases and Pain Management Nitrous oxide, often called “laughing gas,” is a versatile medical gas that’s been used in healthcare for over 150 years. While most people associate it with dentistry, it’s used throughout hospitals for several purposes. In labor and delivery units, nitrous oxide helps manage pain during childbirth while allowing mothers to remain conscious and alert. It’s particularly popular because it leaves the system quickly and has minimal effects on the baby. Operating rooms also combine nitrous oxide with other anesthetic gases to maintain general anesthesia during surgeries. The gas helps reduce the amount of other anesthetics needed, potentially leading to faster recovery times. Specialty Medical Gases and Their Unique Uses Several specialty gases serve specific medical purposes. These gases might be less known, but they’re equally important as oxygen and nitrous oxide. Here are some of the most notable gases you should know about: Carbon dioxide: essential for minimally invasive surgeries. Surgeons use it to inflate the abdomen during laparoscopic procedures, creating space to work and improving visibility. Helium: when mixed with oxygen (called heliox), helium helps patients with severe asthma or COPD breathe more easily. The lighter-than-air mixture reduces airway resistance and makes breathing less laborious. Nitrogen: finds its niche in cryotherapy and sample preservation. Liquid nitrogen’s extremely low temperature makes it perfect for removing warts and preserving biological samples. Quality Control and Safety Requirements Medical gases require strict quality control measures because they’re classified as drugs by the FDA. Storage and handling procedures must follow specific protocols to prevent contamination. Each gas cylinder must be properly labeled and color-coded according to industry standards, for example: Nitrous oxide: light blue Carbon dioxide: gray Helium: brown Regular testing and certification ensure the purity and quality of medical gases. This includes checking for potential contaminants and verifying the correct concentration of gas mixtures. Modern hospitals also have sophisticated gas delivery systems with multiple safety features. These include emergency shutoff valves, pressure monitoring systems, and backup supply systems to ensure continuous availability. The medical staff must undergo regular training on proper gas handling and emergency procedures. This includes understanding the risks associated with each gas and knowing how to respond to potential leaks or other emergencies. Get Medical Gases From Trusted Vendors When it comes to medical gases, there’s no room for error. That’s why healthcare facilities partner with trusted suppliers who understand the critical nature of these products and maintain the highest standards of quality and safety. More importantly, a reliable supplier can provide solutions that adhere to all the necessary regulations and provide guidance on proper handling. Partner with such a vendor, and you can use medical gases without risks.
